I just purchased at $60 add-on for my iPhone which allows me to shoot 360° videos. I haven't calibrated it yet, but out of the box it seems to work. I knew that it would have trouble with focus and I need to do some calibration to improve that. Of course this camera will continue to have limitations even after being calibrated, but it will give me a good idea of what you can and can't do with 360° video.

There are more impressive cameras that are about to appear for sale, including the 360cam by Giroptic (http://www.360.tv/) seen below
